BoKu was marketed as "adult" juice, as juice boxes were commonly attributed to grade-school children because of their small size and easy ability to pack in a lunch. Consequently, BoKu juice boxes were larger, omitted a straw in favor of a pull tab, and was offered in flavors considered more suitable for adults.
BoKu's television ads featured comedian Richard Lewis. Lewis would be seen standing in front of the camera, holding a BoKu box and espousing how the product was suited more for adults than children. At the end of each ad, shortly after taking a sip, Lewis would say to the camera: "Is that too much to ask?!"
